Long runtime P60 drop-ins?

[Illum]

While there's been a lot of threads covering different applications of P60 dropins I've noticed most of them are based on high power
Is there any that runs like the E2L in terms of current draw and heat output?

Anything with a P60L or higher would require the metal bezel to dissipate heat, I was hoping for something that can use with the regular G2 head and doesn't go through primaries or secondaries as fast as these 1A driven R2s

I certainly won't argue with how limited the output maybe. Anything that will run for more than 2 hours is certainly ideal, if even possible:shrug:

Try the M60LL. runs for quite a while and it says on the Mslkoff site that it can run for extended periods in plastic heads.

I have one with a buck boost driver ,,,,

Runs 20mA on Lo to 30mA ... Dep on the batt used .

With a 600mAh batt , thats like 20 hours on Lo ... for a single RCR123A

Solarforce L2M [ mini ]

0.03A Lo
0.35A Med
1.15A Hi

I am very very happy with my M60LL. There is also an 8V custom run LF incan on the marketplace in the group buy section. Long incan runtimes.

+1 & +1.

The M60LL has an output of ~80 lumens and has yielded fantastic runtimes, BigWaffles has measured a regulated runtime of ~18 hours from 2x SureFire primaries:

The Lumens Factory incan is a great LA as well, I have communicated with 325addict and it sounds like a great lamp assembly. Good throw, nice and white, 500 ma current draw, very efficient - high lux for the wattage, from what I've read. And only ~$15 from what I gather, a real bargain.

Edit: Here's a quote from one of his PM's, I don't think he'd mind:

I can tell you, it is about as bright as a P60! The hotspot is a little smaller. Compared to the P90, the color of the light is just as white, only the P90 has even more a wider hotspot, so it lights up a much wider area at once. This is a well known, common feature of all Lumens Factory lamps: they are very well focused, real throwers!

So it looks to be competitive in actual use to a P90, but with considerably lower current draw. A great match with 2x LiIon, unlike the P60 which can't handle the voltage.

Try the new Dereelight 3sm drop in. http://flashlightconnection.com/Der...ns/Dereelight-P60-Drop-In-3SM-5B-Q4--p87.html

I'm using it with a AW 17670 and at the tailcap on low it draws 22.6 mah at 4.2v,44.6 mah with 2 cr123.and 62.5 mah with 2 rcr123. The runtime on medium is 6 hours and 1:46 hrs on high. I haven't done a runtime on low yet but I would guess somewhere around 70 hrs. I would guess the light to produce around 6 lumens on low.

the M60LL sounds nice, I might give that a try when I get to it, from BigWaffles runtime graph it looks brilliant, I'm not sure how I missed out on it:candle:

I'm going to order one and see if it'll do before I go for the Malkoff, as it appears that the M60LL is suited for cr123As, I'm running 1x 17670 in my G2 at the moment.

How do you change modes? just turn off then back on?

:thanks: for the inputs! :thanks:

I know, I try to read everything about the Malkoffs but I missed BW's initial post back in February as well. Just amazing, 80 lumens for 18 hours vs the SureFire P60L, 80 lumens (actually 65 lumens after the thermal limiter kicks in) for only 2.5 hours.
The Malkoffs actually do pretty well on a single LiIon cell. I'm putting together an M60 on 1x18650 and can test my M60LL on the same configuration. I don't anticipate any loss in output with such a low current draw. Mdocod runs his M60L on 1x17670 and also cannot perceive any loss in output.
Good stuff,

I figured looking for sheer runtime I could avoid multimode but I guess I was wrong about that... aha, ahahaha...

Been using the single mode E2L for too long, kinda forgot multimode:shrug:

You can either click it off then on or just hit the tailcap quickly and it will change to the next mode.

What about a single mode long runtime P-60 dropin? I'm talking like 10 lumens with an input of 3.5-9v so I can use 2xCR123, 2xRCR123, or an 18650.

Your asking for a lot ...
You may want to swap out the driver for one that will meet your needs , 500mA or 750mA driver ... Depending on the emitter , a 500mA driver should offer over 100Lumen and give decent runtime .. 4 to 5 hours with a 18650

But nothing will touch a multimode where low draws under 100mA ...
My lowest is right on 10mA on low , and will run a long time on a 18650 , 200+ Hours ..

 

[Justin Case]

A cheap way to go would be to get a DX drop-in of your choice, and swap the driver for a 1xAMC7135 LDO regulator. At 350mA, 1xAW18650 could last about 7 hours.

What drop-in is that?

Ooops , I dont buy many drop ins anymore , I just put together my own .

 

[etc]

Nichia GS 5mm "Battery vampire" mod
Malkoff M60LL

Both will run very well in 1x123 configuration with some crazy runtimes. I cannot quantify it but they are measured in days rather than hours.

I have a 5 mode XPG R5 P60 drop in from DX that cost all of $14.16 (including shipping) and I usually run it in a Solarforce L2P powered by one Trustfire 2400 mAh 18650 (red/black/flame model). I usually run this drop in on medium (which is still fairly bright btw) in candle stick mode for 8 to 10 hours straight most nights and it stays cool as a cucumber (on medium that is. It gets a bit hot on high which draws about 1A). Anyway, when I top off that 18650 battery the next morning, it usually takes between 500 and 600 mA from my hobby charger before the battery is full again. I assume that since the 8 hours runtime on medium is only using about 500 mAh of my batteries capacity, it could probably run 4 to 5 times as long (or about 30 to 36 hours on medium) before depleting my 2400 mAh 18650. So I think that is pretty decent run time from this inexpensive drop in. And if I needed even longer runtime, there is also the low mode which uses a lot less power than the medium mode.

So I give this inexpensive drop in a pretty high recommendation. It also has a very nice smooth beam pattern and is quite bright on high (manufacturer rated @ 320 lumen which it appears to actually produce at a fairly conservative ~1A draw). The main negatives are its cool white tint (would prefer neutral white) and it has SOS and strobe modes stuck in there with hi, med, & low. I would prefer if it only had hi, med, & low. But then, it only cost ~$14 shipped, so I can forgive it those minor flaws. And it's been running about 8 hrs per night for several months now without a hint of any unreliability issues. Really, it's a great drop-in, especially considering the price.
